This was a pretty straight-forward setup as I have done this same project about a thousand times. Here's the general setup for the Exchange Online Piece.

First, we used TechSoup (used for Microsoft non-profit licensing) to get licenses and set up the Office 365 tenant. Then we added the domain of the church and manually set up the users.

Next, we used MigrationWiz to migrate all email older than 30 days from the on-prem exchange to the Office 365 accounts.

Then we cut over the mail delivery location in Reflexion to send email to our new 365 tenant. This part is always the most stressful as users' phones and Outlook clients now need to point to the new location. Once the mail flow is flipped to 365, we then began the final MigrationWiz migration to bring over any remaining email and all other data from the SBS (Calendars, Contacts, etc).

In order to switch the Outlook profiles on an SBS, you must first scrub out the on-prem Exchange Autodiscover Record. Otherwise, Exchange will grab the request from Outlook and it will never make it outside the LAN and to Office 365.

Finally, we changed Outlook accounts and we were pretty much done. Thank God these clients had a pretty simple setup and we hit minimal issues.

Technology Used

The absolute BEST migration tool for email on the planet. Takes a bit to get configured, but once you've done it a few times, it gets pretty easy. They have a great knowledge base too. I use their KB for things I'm doing in 365 that don't even involve MigrationWiz. That's how good and easy to follow it is.
